"failed assessment"

My son is 1 year 8 months, since he was 7 month I have been taking him to the doctors with his ears as he is constantly pulling on them. The doctor never assessed him and just said its normal. After constantly being shrugged off I changed to a different doctors and after being to the appointment with my son he has got inflamed ears which has been causing discomfort to him, I feel the doctors surgery failed to do their job, especially as he was so young when this started. Also, you have to wait weeks for an appointment and wait half an hour to get a reply on the phone. I would definitely not recommend this doctors to anyone.
